A Shift in the Debate Over Global Warming

Most of the focus in the last few years has centered on imposing caps on greenhouse gas emissions to prod energy users to conserve or switch to nonpolluting technologies.

But now, with recent data showing an unexpected rise in global emissions and a decline in energy efficiency, a growing chorus of economists, scientists and students of energy policy are saying that whatever benefits the cap approach yields, it will be too little and come too late.

Tories reject opposition pledge on global warming

OTTAWA – The Harper government has rejected a new pledge taken by opposition leaders to endorse a tough international treaty to fight global warming.

Liberal Leader Stephane Dion, the Bloc Quebecois’ Gilles Duceppe and the NDP’s Jack Layton all signed the pledge to push for a post-Kyoto Protocol climate change agreement that would prevent average global temperatures from rising by more than two degrees Celsius above 19th-century levels “because scientists have shown that, otherwise, the consequences of global warming are likely to be catastrophic.”

Hotter and Drier: The West’s Changed Climate

Human activities are already changing the climate of the American West. This report by the Rocky Mountain Climate Organization (RMCO) and the Natural Resources Defense Council (NRDC), drawn from 50 scientific studies, 125 other government and scientific sources, and our own new analyses, documents that the West is being affected more by a changed climate than any other part of the United States outside of Alaska. When compared to the 20th century average, the West has experienced an increase in average temperature during the last five years that is 70 percent greater than the world as a whole. Responding quickly at all levels of government by embracing the solutions that are available is critical to minimizing further disruption of this region’s climate and economy.
